Outside Bin Hold-Down Charts (4.00" Corrugation)
Outside bin hold-down should be used on all non-stiffened bins. When anchoring the bin, be sure the
vertical seams of the bin align with the U-bolts in the foundation. They may be anchored to the foundation
using either the U-bolt and J-bolt combination or the single anchor bolt, except on the 42' and larger bins
and bins 10 rings tall.
NOTE: All non-stiffened 42' and larger bins and bins 10 rings tall should use single anchor bolts, not the
U-bolt/J-bolt combination. 10 Ring bins require double hold-downs. (Double U-bolt/J-bolt may
be used on non-stiffened 42' and larger bins no greater than 9 rings tall, as an option. Extra
hold-downs are required with this option.)
